WebP Support#

WebP is natively supported in Google Chrome, Safari, Firefox, Edge, the Opera browser, and by many other tools and software libraries. Developers have also added support to a variety of image editing tools.

WebP includes the lightweight encoding and decoding library libwebp and the command line tools cwebp and dwebp for converting images to and from the WebP format, as well as tools for viewing, muxing and animating WebP images. The full source code is available on the download page.

WebP Converter Download#

Convert your favorite collection from PNG and JPEG to WebP by downloading the precompiled cwebp conversion tool for Linux, Windows or macOS.

Using cwebp to Convert Images to the WebP Format#

Use cwebp on the command line to convert PNG or JPEG image files to WebP format. You can convert a PNG image file to a WebP image with a quality range of 80 with the command:

cwebp -q 80 image.png -o image.webp

• -o string Specify the name of the output WebP file. If omitted, cwebp will perform compression but only report statistics.

• -q float Specify the compression factor for RGB channels between 0 and 100. The default is 75.

  In case of lossy compression (default), a small factor produces a smaller file with lower quality. Best quality is achieved by using a value of 100.

  In case of lossless compression (specified by the -lossless option), a small factor enables faster compression speed, but produces a larger file. Maximum compression is achieved by using a value of 100.

• -lossless Encode the image without any loss.

Using dwebp to Convert Images from the WebP Format#

Use dwebp on the command line to convert WebP image files to the PNG or PPM format. You can convert a WebP image file, say image.webp to a PNG image with the command:

dwebp image.webp -o image.png

• -o string Specify the name of the output file (as PNG format by default).
